Marshall mix design was used, first to determine the optimum bitumen binder content and then further to test the mixtures properties of the various filler / asphalt ratio asphalt mixtures. In total, 75 samples were prepared to investigate the optimum asphalt content of the various mixes and to specify properties of them. Five proportions of asphalt cement binder were used for each mix type and state by weight of the total mix (4, 4.5, 5, 5.5, and 6). The tests include the determination of bulk specific gravity, maximum (theoretical) specific gravity, stability and flow. Marshall mix design requires the determination of the percentages of air voids, voids in mineral aggregate, and voids filled with asphalt.
